I see the graph from Google Trends:

Javascript:

Javascript

Why Javascript goes down? Isn't it the most popular script language in web? What maybe replace javascript in the future?

And also Java (vs .net, c#):

Java

Well, both Java and .Net are going down, why? Are there some new wonderful languages better then Java coming out?

I think the real trend is programmers have stopped using Google and started going straight to the Stack... –  eds Jun 6 '11 at 12:45

Google Trends doesn't mean anything. Fewer people are searching for those keywords, but there is no reason to assume that the number of people using that language is linear to the number of people searching for those keywords.

Can you think of a better way to gauge language popularity? –  user21007 Apr 23 '11 at 1:22
    
Maybe "How many new projects have recently been created in this language ?" or, more relevant, "How many job offers require this language ?" –  POSIX_ME_HARDER Apr 23 '11 at 1:31

@user21007: How about the TIOBE index? –  back2dos Apr 23 '11 at 1:54

Fewer searches might also mean increasingly better search results. –  Darien Jun 7 '11 at 20:12
    
@back2dos Isn't the TIOBE index based on search results, just like the question was asking? –  tylermac Jun 8 '11 at 18:14

Libraries like JQuery are another reason searches for JavaScript have dropped dramatically. Fewer people need help with JavaScript due to the benefits of JQuery and they search instead for JQuery. I use JavaScript all the time and rarely perform searches containing the term "JavaScript".

That pretty much matches what I was going to say. Developers in 2011 are much more likely to be doing more specific searches that don't involve the word "JavaScript". –  Carson63000 Apr 23 '11 at 5:33
